FIGURE 6.

Evolution of the distribution of fiber orientations Ψ at three energies of interaction with external electric field, indicated in the plots. φ, angle between fiber dipole moment and direction of electric vector of optical field. Since fiber dipole moment is perpendicular to fiber axis, the fiber orientation is shifted by π/2 with respect to those shown here. Fiber growth with rate R = 1 μm s⁻¹ increases dipole moment, μ, and length, L, and changes rotational diffusion coefficient according to the expression in the text.
